5. Troubleshooting

If you encounter issues with your BENFEI DisplayPort to HDMI adapter, consider the following troubleshooting steps:

• No Signal / Blank Screen:
  • Ensure both the DisplayPort connector and the HDMI cable are securely plugged into their respective ports.
  • Verify that your source device (computer/laptop) has a DisplayPort output, not an HDMI or USB port. This adapter is uni-directional (DP to HDMI).
  • Check the input source on your monitor/TV to ensure it's set to the correct HDMI input.
  • Try restarting your computer or display.
  • Test with a different HDMI cable or display if possible, to rule out other component issues.
• Flickering or Intermittent Signal:
  • Ensure all connections are firm. The DisplayPort connector has latches; make sure it's fully engaged.
  • Reduce the display resolution or refresh rate in your computer's display settings to see if stability improves.
  • Check for any physical damage to the adapter or cables.
• No Audio:
  • Ensure your computer's audio output is set to the HDMI display. This can usually be found in your operating system's sound settings.
  • Verify that your HDMI display supports audio input.
• Incorrect Resolution or Aspect Ratio:
  • Adjust the display resolution and scaling settings in your computer's operating system.
  • Ensure your display supports the desired resolution.
